TYPE-WRITING MACHINE.

SPECIFICATION forming part of Letters Patent No. 578,679, dated March 9, 1897.

Application filed July 20, 1895. Serial No. 556,576- (No model.)

To all whom it may concern.- nal-studs c and c are supported, respectively, Be it known that I, ZALMON G. SHOLES, a by the standards F and F, each of these citizen of the United States, and a resident standards consisting, preferably, of a single of Evanston, Cook county, Illinois, have inmetal plate having outwardly-turned feetf, 55 5 vented certain new and useful Improvements whereby the standards may be attached to in Type-\Vriting Machines, of which the folthe top of the carriage A. The standard F lowingis hereby declared to be a full, clear, is shown as provided with a hole f to receive and exact description, reference being had to the journal-studs o of the platen-frame, while the accompanying drawings, forming a part the standard F is provided with an open jour- 60 I of this specification. nal seat or socket f to receive the journal 0 The present invention has relation more at the opposite end of the platen-frame.

This latch-plate is formed at its front in the accompanying drawings, and particuwith a suitably-arranged hook g, adapted to larly defined in the claims at the end of the pass over the end of the journal 0 and thus 75 specification. prevent the slipping of the journal from the Figure 1 is a plan view of a paper-carriage journal-seat f of the standard F.

When the projecteratortomake correctionstherein. Thejouring platen is in its upturned position, the

platen-journal b is shown as extending beyond the platen-sustaining frame suflicient distance to be engaged by the latch-plate G. Thus, for example, if the platen B and'its sustaining-frame be turned from the position shown by full lines in Fig. 2 until the platen shaft or journal 1) enters the recess at the base of the extension f the latch-plate G can be turned downward until the hook g closes around the platen shaft or journal I), and thus securely locks the platen -frame and platen in its upturned position. The opera tor can then easily shift the paper or make corrections in the work without danger of the accidental downward turning of the platen and its sustaining-frame.

In order to better retain the latch-plate G in the difierent positions to which it may be turned, I prefer to form this plate with a slot 9 through which passes a headed pin 0, carrying a friction disk or washer r, the disk or washer 7" hearing against the outer face of the latch-plate Gwith sufficient force to guard against the accidental shifting of the latchplate.

It is manifest that the precise details of construction above set out may be varied within wide limits Without departing from the spirit of the invention. Thus, for example, while I have shown the platen B as mounted within a tilting frame that is journaled upon studs, it is obvious that my invention may be used in connection with other convenient means whereby the platen may be turned in order to expose the line of printing.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. In a type-writer, the combination with a rotary platen and with means for turning the same to expose the line of printing, of a latch for locking the platen when turned to position to expose the printed line, said latch being normally out of position to lock the platen as said platen is shifted to expose the print, but being manually movable into fixed position to lock said platen when it is upturned to expose the print, substantially as described.

2. In a type-writing machine, the combination With a platen and with means for turning the same to expose the line of printing and with a suitable part projecting therefrom and movable therewith, of a latch for locking said platen when upturned to expose the print, said latch being pivoted to swing forward and being provided at its front edge with a forwardly-projecting open hook or extension adapted to be manually moved in front of said projecting part in order to rigidly retain said part until said latch is manually shifted out of its path, substantially as described.

3. In a type-writing machine, the combination with a platen and its tilting sustainingframe whereby said platen may be upturned to expose the line of printing, of a latch whereby the platen-frame may be locked when turned to expose the printed line, said latch being normally out of position to lock the platen as said platen is shifted to expose the printing, but being manually movable and being provided at its front with a forwardlyprojecting open hook whereby the platenframe may be rigidly locked in its upturned position, substantially as described.

4:. In a type-writing machine, the combination with a rotary platen and its tilt-ing sustaining-frame, of a pivoted latch-plate G for sustaining said platen-frame in upturned position and a suitable friction device engaging said latch-plate and serving to hold it in any position at which it may be manually set, substantially as described.

5. In a type-writing machine, the combination with a rotary platen and its tilting sustaining frame, of standards wherein said frame is journaled, one of said standards being provided with an open seat, and a latchplate having at its front one hook or extension to obstruct said open seat and having at its front another hook or extension to retain the platen-frame in upturned position, sub stantially as described.

6. In a type-writing machine, the combination with a platen and its tilting sustainingframe, of a pivoted latch-plate formed with a slot, a pin within said slot, and a hook or projection extending from said latch-plate and serving to retain the platen-frame in upturned position.

'7. In a type-writing machine, the combination with a rotary platen and its tilting sustaining-frame, of standards wherein the journals of said sustaining-frame are mounted, one of said standards being provided with an open seat, and a pivoted latch-plate G havinga hook or extension g to retain the platenframe journal in position and having a hook or extension 9 to engage the projecting end of the platen-journal when the platen-frame and platen are turned to expose the printing.
